Intelligent mine mining model test system under multi-field coupling

Abstract

The invention discloses an intelligent mine mining model test system under multi-field coupling. A combined sealing reaction device comprises a combined frame, and reaction wall modules are arranged on the front side and the rear side of the combined frame; a high-precision real-time synchronous monitoring system directly faces the front side of the sealing reaction device so as to collect imagesof a test process; a dynamic and static combined high-precision hydraulic control system comprises multiple boundary energy storage oil cylinders which are arranged at the top and on two sides of thecombined frame, the boundary energy storage oil cylinders are connected with a hydraulic power unit, and the hydraulic power unit is connected with a controller; an intelligent tilted stratum simulation device is arranged at the bottom of the combined sealing reaction device and can jack up the combined sealing reaction device to make it tilt; an automatic coal mining and roadway profiling drivingsystem is arranged on the rear side of the combined sealing reaction device to simulate roadway driving and coal mining; and a cut joint simulation device is located in a model to truly simulate cutjoints.

Description

technical field [0001] The disclosure belongs to the technical field of mine mining model tests, and in particular relates to a multi-field coupled mine intelligent mining model test system. Background technique [0002] In recent years, with the gradual depletion of shallow resources, coal mining has continued to develop to the deep. As the excavation depth continues to increase, roadways often face adverse geological conditions such as high ground stress, high osmotic pressure, extremely soft rock, and fault fracture zones, which can easily lead to frequent disasters, roof caving, and large deformations in deep roadways during construction. Concealed and sudden safety accidents, such as bottom slop, water and mud inrush, etc., cause major safety accidents and economic losses. In order to ensure the safe production of coal mines and improve the economic benefits of coal mines, it is necessary to fundamentally understand the deformation and failure mechanism of deep roadway...

AI Technical Summary

Problems solved by technology

[0003] (1) Most of the model test systems at home and abroad use homogeneous materials, and less consideration is given to the influence of simulated inclined rock formations

[0004] (2) Model test systems at home and abroad are mostly manual excavation, and it is difficult to simulate the automatic excavation of roadways of different shapes and sizes and the automatic mining process of the working face

[0005] (3) Most of the domestic and foreign model test systems can only simulate one or two complex geological conditions, and cannot simultaneously simulate mines under the combined effects of high ground stress, high seepage flow field, inclined rock formation, rock burst, coal and gas outburst, etc. mining process
